-
- si=27160-(principal amount)=27160-22000=5160.
now,(10000*5*R/100) + (12000*3*R/100)=5160.
500R+360R=5160.....Rate=6%. - 8 years agoHelpfull: Yes(25) No(0)
- ans is b
interest charges on 10000 for 5 yeras and charges on 12000 for 3 years
let the rate of interest be x per annum
10000+5(x/100 * 10000)+12000+3(x/100*12000)=27160
on solving we get x=6 - 8 years agoHelpfull: Yes(11) No(0)
